Kibblewhite Valve Spring Kit for Suzuki DR-Z 400 2000-2004 - High Performance Motorcycle Engine Upgrade for Off-Road & Trail Riding

Kibblewhite designs their valve spring kits with a "system" approach that ensures excellent performance by optimizing each piece to work together as a set. The dual valve spring orientation reduces valve float at high rpm and after extended hours of riding since the Kibblewhite springs are made of resilient chrome silicon spring wire. The kit contains titanium upper collars, lower collars, and seals, all of which are subject to the same rigorous Kibblewhite standards and manufacturing processes like heat treating, shot peening, and stress relieving.

Sold as complete kits for one motor.
